摘要:

本文在漏电介质模型的框架下研究了均匀直流电场中液滴的成对相互作用。我们开发了三维数值模拟使用边界积分方法和分析理论假设小滴变形。我们应用模拟和理论来探索两个相同的液滴与任意取向的中心线相对于所施加的场方向的电流体动力学相互作用。我们的研究结果显示了复杂的动力学依赖于液滴和悬浮液的电导率和电导率,以及初始液滴对与所施加的电场对齐。

英文摘要:

We study the pairwise interactions of drops in an applied uniform DC electric field within the framework of the leaky dielectric model. We develop three-dimensional numerical simulations using the boundary integral method and an analytical theory assuming small drop deformations. We apply the simulations and the theory to explore the electrohydrodynamic interactions between two identical drops with arbitrary orientation of the their line of centers relative to the applied field direction. Our results show complex dynamics depending on the conductivities and permittivities of the drops and suspending fluids, and the initial drop pair alignment with the applied electric field.
